Gimbaling Collet Chuck
February 1, 2016
Northfield Precision Instrument Corporation, a designer and manufacturer of precision workholding chucks, has designed a special gimbaling collet chuck. This chuck uses a precision collet to grip the pitch diameter of a splined drive shaft for balancing. The collet taper is ground inside a sphere, which is then installed to the mating sphere, allowing the collet to "gimbal."
"When a drive shaft is placed in a balance machine, it `whips' due to the unbalance. If the chuck holds the shaft rigid (not allowing whip), the shaft is falsely balanced with poor results. This gimbal chuck cuts the balance cycle in half with enhanced accuracy," said a company spokesperson.
Northfield Precision Instrument designs and manufactures air chucks for any lathe, boring machine, grinder or VMC. Models include through-hole, high-speed and quick-change. Chucks are available in SAE or metric, in sizes from 3" (76 mm) to 18" (457 mm). Accuracies of 0.001" to 0.00001" (0.254 m) are guaranteed. Custom workholding chucks and jaws are available and free engineering assistance is offered.
